Application filed February 6, 180%. Serial No. 192, 38.

To all whom it may'con'cem:

Be it known that OTTMAR Mnnonnrnailnn, late a citizen of the United States, and a resident of the city of Balt-in'iore, in the State of Maryland, now deceased, did invent. certain new and useful Improvements in Typographic Machines or Machines of Similar "Character. of which the following is a specification.

This invention relates to machines for pro-'- ducing printing surfaces, and more particularly to that .class thereof in which are formed lines of logotypes or integral words in place of single type or 'linotypes, thus substituting the word as the unit of matter for the individual letter or complete line. Each of the words or logotypes thus formed is cast with the properspacing blank attached thereto, so that when assembled they form justified matter.

The invention consists in theconstruction and combination of parts as described in the specification, illustrated in the drawings, and finally pointed out in the claims.

Many of the features of the invention are capable of extensive application, although forthe purpose of this case it is shown in connection with an organized machine; but it will be understood that different applications thereof may be made, and that/many changes and variations therein are possible without departing from the spirit of the invention.

The general operation of the organized machine is specifically as follows: The characters are arranged and the line is comwords of outside dimensions which overreach the matrices at the top and-bottom. lVhen the line contains as much matter as it will take or is desired, a lever is operated whose first act is to liberate the line delivery slide thus causing the slide to compress the line against a stop bolt in the assembling or delivery channel. The further ddwnward movement ofthis lever causes a test gage to be inserted between the last.- matrix and the theoretical end of the line, which action atiects the casting apparatus in 'a way to be described later. On the return stroke of delivery channel and the line moves up to the casting mechanism while the front. gate in the delivery channel returns to itsorlginal position. The operator proceeds to set the next line while the casting apparatus now starts to cast wordafter word of the line presented to it, The starting of the casting mechanism is effected by the line in its motion to the left arriving on'the start;

ing pin and pressing the latter backward with the effect] of detentmg the. machine. in

this position the first word has entered-a, reciprocating,slide while the further IDQUOHH of the line is arrested by the space blank and matrices composing the first word press.

ing against the slide and. the detenting pin respectively. The slide now moves the first word toward the mold, the jaws close up on it, the metal is injected, and the matrices are then moved through the slide and on to the intermediate elevator, from which in turnthey are transferredto the regular elevator. The mold moves to the left so as to clear obstructions for the ejection of the type and to obtain suitable room for the galley. These operations'will repeat themselves until the-last word of the presented line has been received and disposed of, when the apparatus will come to rest.

'' The general operation of the means for delivering the assembled line to the presentation slide is follows: The delivery slide and its movable gate normally occupy a position' with the latter in line or even with the end of the line to be composed Near it is a movable gate or yielding resistant which prevents the matrices from turning over and recedes as the composition is progressing.

The measuring device or test gage crosses the end of the line and is opened one tooth every time a space blank is inserted. When the line has as many words as it will take, the starting lever is operated, and its first action is to trip the pawl and detent the line delivery slide which carries the line. to the left until arrested by the movable stop. The line will now rest until the test'gage through the. action of the starting lever has been carried far enough across the end of the line to take up all the space left unfilled, when its further motion will cease, and the starting lever then continues its motion until. it has withdrawn the movable stop," thus liberating the line completely and allowing it to be carried to the casting mechanism. Vhen it an rives there a reciprocating piece or shover forces the front gate below the assembled a tification. The underlying idea involved in- -this mechanism is to ascertain the total;

' line, when it retui'n'sto its normal position Then the.

in readiness for another line. last word of the line has been delivered to the casting apparatus, the rear gate of the -.line'deliver'y slide is acted upon by the 're-' position at the left contacts with a detenting mechanism and thus liberates a cam shaft by the action of which 1 0 18 returned to itsoriglnal position where it may be replaced in the 'line by an armon the starting shaft. f A t Reference has been made to the use of a test gage for the purpose of efi'ecting the jusamount of space left unfilled in the line, to divide it by the number of spaces the line contains, and to addthat amountof space to each word. This end is accomplished in the following manner: The test gage is formed of two pieces and normally has parallel sides. W'hen'a space blank is inserted in the line the test gage is opened a given amount so as to make it 'a-wedge. In other words, it represents a single space, andeach further space blank introduced in the line opens the wedge to the same extent, so that when the line is completed the taper of the wedge is in proportion to the number of space blanks in the line. It follows'from this that if we use a wedge as one of the vise jaws atthe caster,.of a taper proportionateto the taper given the test gage by theactionof a single space key, and cause the justifying wedge or jaw to move the same distance that the test gage travels through the line, accurate justification of all the words comprising that line must be obtained automat-v ically by the action of the casting apparatus.

The wedge or vise jaw is returned by the ac tion of the delivery slide before the .last word is cast that word requires no space, due to the fact that the number of justifying spaces' in the line is one less than the num'-' ber of words. Referring now to the drawings: Figure 1 is a front view of a sufficient portion of the organized machine to show the application of the invention thereto.

shown in Fig. 7 and are all (except the last one) formed with a justifying or spacing portion integral therewith, so that when assembled they fill out the predetermined lengthv of line and form j'ustified matter. The characters for the entire line'are arranged at one time, the. line consisting of a plurality of individual letter matriceswith thin space blanks between the words. thus constituting a line of word matrices, each word matrix being formed'of the necessary letter matrices and the thin space blank at The matrices and space blanks are assembled so as to fillout as far as possible the prescribed measure, and the word matrices are subsequently separated one byone, and the logotypes -cast individually and consecutively therefrom. The space remaining to be filled out in the-assembled line is apportioned among the several logotypes and cast thereon, the justifying space onjeach logotype being that represented by the space blank thereof and the apportioned amount added thereto. It therefore "follows that each of these logotypes is longer than the corresponding word matrix, and that the assembled line of logotypes is longer than the assembledline of matrices and space blanks. As the number of spaces necessary to justify the line is one less than the number of words, the last logotype is cast without the justifying spaec and istherefore of the same length as the corresponding word. matrix. 1

Matrix and spam 7 Zm/n.'The specific forms of the matrices and space blanks em-,

ployed in this machine are unimportant, although for purposes of illustration such forms have been selected as are illustrated in trix used in connection with the commercial Mergenthaler linotype machine. The thin space blank H, as shown, somewhat longer than the matrix and is formed with an interior recess H to engage the rod T", and a slot H as permit the space blank to pass the 'sTlfpportsT T of the rod T ing means known in the art could be used,

. such for instance as those described and illustrated in the ll. Letters-Patent to ()tt; mar Mergentlialer, Nos. 345,526; 347,629;

The matrix G is provided with dis- 'tributing teeth G and is simllar to the ma- M7530; 378,797; 378,798; 392,446; 436,531; 436,532; and 678,268. For the purposes of illustration means are shown herein somewhat similar to those presented in the last mentioned patent No. 678,268, and thisgeir 'eral organization of machine has been folof the star wheel E. After the matrices have passed through the casting mechanism theyare transferred to the mam elevator L, which moves from lts lowermost to its distributing position on the vertical shaft M,

these movements being imparted to'the elevator L by the cord and pulley arrangement JJ. In the upper position of the elevator L the matrices G are moved by the shifter slide N into engagement with the distribut i'ngv devices KK, all as described in the patent referred to. Similarly, any suitable means may bflGIHPlOYt-sd to deliver and restore the space blanks, although for the purposes of the present case a special form of device is illust-ratechas best shown in Figs. 1, 3, 3 3 4 and 8. The space blanks H formed with. the recesses H and H are stored upon a curved rod T fastened at one end immediatelyabove the delivery point by a bracket T and at its other end by a simi lar bracket T in proximity to the presentationslide W. Any. suitable form of escapement may be employed in connerfiion with the curved rodT the oneherein illustrated being somewhat similar to that shown in the before mentioned patent No. 678,268. The space blanks H are held by a projection at the end of the rod T*' with their lower ends restingagainst the side plate T of the delivery chute, and are freed from the rod T one at a time, by the action of the escapement T. which is held in close relation with the wall- T by the spring T and is actuated i and T7 of the delivery chute into the assem- .bling channel F in front of the star wheel E. In. the present instance the space blank delivery mechanism is not shown aslocated in the same vertical plane with the matrix delivery devices and its chute is therefore properly inclined (see Figs. 3 and11) to deliver the space blanks at the proper point.

After the words are cast, the spaceblanks H are ejected, one by one, from the presentation slide \V by the rod 72 (see Figs. 3, 3

4 ,.and 8), whichpushes the space. blanks H on to the rod T, and they descend by gravity to the lowest point of the rod T, where they are engaged by a finger U on the ro-- tating wheel U and are thereby restored to their original position readyfor further employment. Motion is imparted to the wheel U by the pulley Z belt Z and pulley Z on the shaft 2?, as hereinafter described. This connection causes'the constant rotation of the wheel U, which however maybe arranged to rotate intermittingly if desired. It will be seen that the devices shown for handling the space blanks might also be adapted to matrices with suitable inodifica-,

tion.

It will be noted that the machine illustrated embodies the circulating system, that or to any specifiemechanisms for handling is to'say, the matrices and space blanks are returned to their places of storage by a path different from that pursued by them during assemblage, and further that the matrices are I independent and free as distinguished from suspended or captive matrices. The pace blanks are similarly free when released by the escapement and remain free until ejected from the presentation slide when they are suspended until again released. But as before noted, this invention is not limited to any specific form of matrix or space blank them.

Transfer, m'e0ham'sm.The matrices G and space blanks H are delivered in the as-. sembling and delivery channel F (see more particularly Figs. 3 and-4*) between the star wheel E and the front gate or yielding resistant 5. The star wheel may be operated as shown in U. S. Letters-Patent to ()ttmar lvlergenthaler, No. 078,268,. so as to lllSlllB its constantrotation and action upon the rear-of theline m course of. as-

semblage in the manner well understood.

" arrangement 2o 2?) connected to the spring 24, the force of which is insufiicient to resist the forward pressure of the star wheel E exerted on the front gate 5 through the matrices and space blanks in the assembly channel. The front gate 5 is-capable of a vertical, movement relative to the slide 11 in which it mounted, it being formed with depending rod which fits in a corresponding cylindrical recess in the slide 11 so as to be capable of a frictional movement therein. The lower part of the gate is I provided (see Figs. 4? and 9) with a projecting piece 15 which controls the vertical adjustment of the gate 5 in the slide 11 in the manner, hereinafter to be described.

The slide ll is mounted upon the guiderod cylindrical recess inthe slide 3 so as to be capable. of vertical movement therein, and is provided at its lower end with a projecting piece 14 which controls-the vertical adjustment of the gate 4 in the slide 3. The slide3 when released in the manner hereinafter to be described is normally pressed toward the left-hand end of the delivery channel'F'by the spring 27 (see Figs. 1, 2 and-18) connected-to the lever 28 at one end of the rock shaft 31, the other end of the rock shaft 31 being connected to the delivery slide 3 by the arm 26 and link 30. The return movement of the slide 3 to its right-handv position is ef-; i

fected bythe lever 28 and cam 29 on the upper cam shaft 8. The particular means employed to effect the movements of the delivery slide, as described, are substantially the equivalents of those presented in Letters-Patent Nos. 436,532 and 557,000. The

slide 3 is held in its initial position by the spring actuated pawl 6 (see Figs 1 and 3) suitably pivoted to the frame and engaging a pin on the slide 3. The starting lever 1' is fast on the -rockshaft- 37 (see Figs. 1, 2, 12 and 15). "An arm 43 (see Fig. 12) is loosely mounted upon the rock shaft 3?, and

offset projection at its outer'extremity' v so located that in its upward movement the projection 100 will engage the lower end of gate 4 and raise it to its operative position in the slide/3 behind the assembled line of matrices alongside the last matrix delivered V to the line, and the further movement of the arm 9 will trip the pawl 0 so as to free the delivery slide 3 whereupon the spring 27 will advance-it toward the casting mechan: ism, the spring 27 being sutliciently strong to overcome the effect, of spring 24,-connected as described to the slide 11.

It will be understood that. while the line of matrices is being assembled, the rear gate 4 remains inactive below the assembling channel F but at the rear end thereof ready 'is connected thereto by a spiral spring 44 prevented by the movable lino stop or bolt H which projects across the delivery channel r (see .n'igs. 3, l and 10) and therefore arrests the movement of the gate 5. The

1 line stop or bolt in may be of any suitable or desired construction, but for purposes of illustration the form presented in the Patout No. (378.2138 has been shown in the drawings, and consists of a bent arm S adjustably mounted upon the rock shaft S a spring S being also connected to the rock shaft S in suchmanner as to hold the stop :-3 across the channel F unless removed therefrom in the manner subsequently to be described. The capability for longitudinal adjustment of the arm S on rock shaft S can ables the length of line to be altered at Will.

l!( .'.noin devices-{t is at this point of the operation of the machine that the shortage in the assembled line is measured by the lust gage or angle bar now to be described.

The particular form. of measuring device or leSt gage employed may be varied considerably without departing from the spirit of the invention. for instance. somewhat similar devices are presented in the U. S. Letters-Patent to F. A. Joln1son,.Nos. 163,388,

384.361. and 607,045, and to Vi. Berri. No. (512,010. The present embodiment of the measuring device is best illustrated in Figs. 3. 11 and 12. and comprises a main branch 2 arranged horizontally on the framework and projecting through a slot 99' immediately above the star wheel Pl (see also Fig. l"). movable member 16 is pivotally connected to the main branch :2 and a spring 17 is interposed between thetw'o members, the normal tendency of whicli'is to hold the part 16 in parallelism with the part 2. The outer end of the member 'lti'is provided with a toothed projection or segment 18 and a spring pressed detent 19 on member 2 engages therewith and thus holds the member 16 in its adjusted angular position against the pressure of the i-spring 17. An elbow l ver i fl-carryii an actuating pawl 21 is pivoted to the .li inc-work in closeproximity to the toothed projection 13. The el-. bow lover is. norn'iallypressed.outward bv the s ring 101. its farther end being then located in the path of the plate Ail-upon the symceblank rod T ('see Figs. 3 and 1.1). it thus follows that each time a space blank s introduced into the line. through the connections described. the member 16 will be i e extent of one of the teeth on "i by the pawl 21 and held in .on by the detent 19. in other words, the angularity of the Wedge will depend upon the number of Words in the line.

'Atter a line hasbeen assembled and moved forward in the manner previously described against the stop S, the test gage is advanced through the slot- 99 behind the rear gate 4;

until its further movement is prevented by the contact of the extended member 16 with the said gate, the stop S serving as an abut ment at the front end of the line and the slot 199 in the framework at the rear end of the line. This motion is'imparted t0 the lest by the arm 19 fastupon the starting shaft 37- and connected to the member 2 by a. link 102 (see Fig. 12). The extent of the motion of the test gage through the line obviously depends upon theangularity oi the wedge. and because of its rigid connection thereto the movement of the rock shaft 37 will be similarly limited, and through the mechanism subsequently to be described the. justifying wedge member or clamping jaw a r? at the casting mechanism is correspondingly set to effect the proper and equal usti: fication of all the words presented to it. A spring pressed piece 20 (see Fig. 3 is pivoted to the frame in proximity to the member 16 and so arranged that in the forwardmovement of the test gage it will be moved out of. the way against the force of its spring by the'rear end of the pivoteddetent 19. When the test gage is afterward withdrawn to its normal position the rear end of detent 19 will again contact with the piece 20, the outer end of which rests upon analiutment- 103. thusefi ecting the pivotal movement of detent 19. the release of the toothed segment 18 lilIGIBfYOITLfiDCl the restoration of the member 16 to its normal parallel position by spring 17.

J ustfy z'ng mom ber.-The justifying wedge member 47 which constitutes one ofthe mold jaws (see Fig. 12) is adjusted by the arm 46 pivotally mounted on the rod 4:8 and connected to the starting shaft-37 by the arm 45 rigidly mounted thereon. As previously explained the extent 9f rotation of the shaft 37 is limited by the movement of the test gage and therefore the upward adjustment of the justifying wedge member always exactly proportionateto the movement of .the test gage. In other words. the position of the justifying member is controlled by the number of intervals between the words of the line and the full measurement of the assembled line. The proper relative proportions of the test gage and ustifying member are matters of simple calculation, it being
